About this document

This document is published by Ofwat under rules 11 and 12 of the Charging Rules for New Connections Services (English Undertakers).

It sets out:

• The common terms and definitions agreed between Water Companies and stakeholders for use by Water Companies including SmallCompanies (where appropriate) in their Charging Arrangements (in addition to those set out in the Charging Rules for New ConnectionsServices (English Undertakers)) issued by Ofwat; and

• the information requirements in a standard format that each Water Company (with the exception of Small Companies), as a minimum,must follow when presenting their Charging Arrangements.

The format for presenting the worked examples has been agreed collectively by companies, in consultation with stakeholders, during 2021. Any company wishing to present their Charging Arrangements using a different format or different worked examples may do so in addition to their obligations under these rules.

This document is approved and published by Ofwat on its website.

Ofwat may amend this document from time to time.

Common terms

Water Companies are required, where appropriate, to use these terms as defined in their Charging Arrangements. Where a term is defined differently in this list of common terms from in the Charging Rules for New Connection Services (English Undertakers), this is because the definition here is phrased so as to be less legalistic and more intelligible to stakeholders rather than to alter its meaning. For the avoidance of doubt, in the event of a conflict between these common terms and the Charging Rules for New Connection Services (English Undertakers) or any statutory provision for the purposes of determination, dispute or other regulatory action by Ofwat, then the latter shall prevail.

Administration Fee

means the fee associated with general administration activities, after the cost advice stage, relating to the construction phase, which can include processing any payments, scheduling the works, supervision and project management, and processing information into relevant billing/management systems. This would not include site-based activities covered in construction costs, such as additional site visits.

Adoption means the process whereby assets are vested in the water company and subsequently maintained at its expense.

Alternative Point of Connection

means another location indicated by the Water Company which is neither i) a practical location indicated by the Developer Customer, nor ii) the nearest practical location where the existing Water Main or Sewer is the same size or larger than the new connecting Water Main or Sewer.

Annual Contestability Summary

means the standard format document published annually (or more frequently) by the Water Company on its website setting out which work and services are Contestable Work and Services and which are Non-contestable Work and Services as described in section 3 of the Water Sector Guidance (see www.water.org.uk/water-sector-guidance-approved-documents/).

Application Fee means the fee levied at point of application, which is associated with upfront application processing, which can include reviewing and acknowledging an application, checking that all relevant information has been received, preparing a cost advice, an agreement or the acceptance for the proposed works.

Barrier Pipe means a polyethylene (PE) pipe with an aluminium barrier layer conforming to water industry specification 4-32-19.




3

Bond or Surety means a cash bond or financial guarantee underwritten by an appropriate warranty provider, bank or insurance company, which is accepted by the Water Company.

Branch Connection means the connection of new pipework to an existing Water Main such to provide a supply of water to a Development.

Communication Pipe

means any part of a Service Pipe which a Water Company could be, or have been, required to lay under section 46 of the Water Industry Act 1991. Typically, it consists of a pipe laid from an existing or newly laid Water Main to the boundary of a property and may include a meter housing and / or external stop valve. This can be seen in figure 1.

Figure 1:

Contaminated Land means land by which a water company will install or request the installation of barrier pipe, following review of the previous use of site, or where proven necessary, in accordance with section 78A of the Environmental Protection Act 1990.

Contestable Work means the work or services that can be completed by either a Water Company or an Accredited Third Party, with the work and services relating to the provision of water supplies defined in each Water Company’s Annual Contestability Summary. For work related to new sewerage services, the majority of work is considered contestable, excluding diversions and requisitions.

Design Checking Fee means the cost of checking a design submitted by an Accredited Third Party.




4

Design Fee means the cost of designing against the application, providing a detailed site drawing and design, specification and cost-advice. This may also include activities identified in the Administration Fee (such as site visit) if that cost is not already charged by the particular Water Company.

Far Side Connection means a connection between premises and an existing water main on the opposite side of the street to those premises, to a maximum communication pipe length of distance of 18 metres, for which a straight linear meterage rate is not applied. Where the water main is located in the centre line of the street then the connection will be considered a Far Side Connection.

Fire Supplies means supplies provided solely for fire safety provision.

Fixed Charges

means charges which are fixed in amount or which are calculated by reference to a predetermined methodology set out in a Water Company’s Charging Arrangements, the application of which allows calculation at the outset of the total amount owing in a given Charging Year in respect of the charges in question. For the avoidance of doubt, a Water Company may impose Fixed Charges by reference to a unit measurement (for example, per megalitre). Furthermore, a Water Company may offer more than one Fixed Charge in charging for a service provided in accordance with the present rules (for example, by differentiating between different geographic areas).




5

This term is autonomous from any incentives applied against the infrastructure charge, for water efficiency for example. These are defined in the term Water Efficiency Incentive.

Infrastructure Charge means the charges described in section 146(2) of the Water Industry Act 1991. That is, a charge paid by the Developer Customer to the Water Company when a property is connected to the company’s water supply or sewer network for the first time. The charges fund wider network reinforcement to meet the increased demand arising from the new connections.

Manifold Connection means where a Communication Pipe connects with a manifold to which separate Supply Pipes are connected and meters may be fitted.

NAV

means a company appointed by Ofwat through the new appointments and variations process to provide water and/or sewerage services to customers in an area previously served by the incumbent Water Company. A new appointment is made when Ofwat appoints a company for the first time to provide services for specific geographic area. A variation occurs where an existing appointment is varied to amend the area served.

Near Side Connection means a connection between premises and an existing Water Main on the same side of a street to those premises. Where the Water Main is in the centre line of the street then the connection will be considered a Far Side Connection.

Network Assembly means components such as sluice valves or washouts, including associated chambers, needed to operate and maintain a water network.

Network Reinforcement means work to provide or modify such other specified types of infrastructure (mains and tanks, service reservoirs, pumping stations, or sewers) as is necessary in consequence of the need to provide adequate water supply and/or sewerage capacity to a development at which mains, service pipes, public sewers and/or lateral drains have been installed or connected by the




6

company imposing the charge or by a company with whom the company has entered into an agreement for bulk supply or bulk discharge.

Non-contestable Work means work or services that can only be completed by the Water Company (or an agent acting on their behalf) and, in the case of work or services associated with the provision of water supplies, is defined in each Water Company's Annual Contestability Summary.

Pre-Planning Enquiry means an enquiry submitted by a Developer Customer to understand the infrastructure requirements or considerations for proposed developments.

Pre-Planning Enquiry Response

means a report by the Water Company in response to a Pre-Planning Enquiry that will confirm i) if the development can be supplied with water, ii) capacity within the wastewater network, iii) if any reinforcement work will be required to supply the site together, iv) and, if applicable, identify any existing assets crossing the site which may require diverting or protecting, and v) if Network Reinforcement is required to supply the site, what indicative capital cost or range of costs is likely for these works.

Relevant Multiplier means a calculation to determine the Infrastructure Charges payable relating to Non-household Premises or Household Premises subject to a common billing agreement and is based on the number and type of water fittings proposed for those premises.




7

Road means a hard-surfaced area intended for vehicles.

Self-certification means the activity whereby an Accredited Third Party inspects, checks and certifies installations, both internal and external to a premise, as being compliant with relevant standards and requirements.

Service Connection means the joining of a Service Pipe to a Water Main which is provided under section 45 and 46 of the Water Industry Act 1991.

Service Pipe means a pipe, which is, or is to be, connected with a Water Main for supplying water from that main to any premise. This can be seen in Figure 1.

Figure 1:

Information requirements

With the exception of Small Companies, each Water Company must present its Charging Arrangements using worked examples for the following scenarios, and in the standard format set out below.

Scenarios summary

Each Water Company should represent the following six scenarios in worked examples in its Charging Arrangements.

1. Single connection to a house from an existing main. 2. Single connection to a block of flats from an existing main. 3. Medium housing development requiring new mains and communication pipes (excavation and reinstatement by others). 4. Medium housing development requiring new mains and communication pipes (excavation and reinstatement by Water Company). 5. Large housing development requiring new mains and communication pipes (excavation and reinstatement by others). 6. Large housing development requiring new mains and communication pipes (excavation and reinstatement by Water Company).

Guidance for Water Companies

For the avoidance of doubt, worked examples should include every charge that the Water Company would impose in accordance with these rules, including where applicable in any of the scenarios:

• Requisition Charges; • Infrastructure Charges; • Connection Charges; • Income Offset;




11

• Relevant ancillary charges; • Clearly itemised unit costs for all relevant services.

Each Water Company should include in its worked examples:

• Adequate commentary to avoid inappropriate comparisons between Water Companies and in any place where the Water Company has chosen to take account of its own specific policies or area-specific terminology and practices.

• Any additional scenarios where the Water Company identifies issues with the scenarios or to highlight specific items that it considers could be of particular interest to its customers.

• Diagrams where the Water Company considers that this will make the worked examples more accessible to Developer Customers.

For all scenarios, when presenting worked examples:

• Assume typical soil type for your region, that there is no rock and the land is not contaminated. • Include all charges for activities and materials expected in an average job in the surface type being used • Include all relevant ancillary charges, such as (but not limited to) application and design fees, any other administrative fees charged

to developer customers for delivering the service, and meter costs and installation (where not included in the Connection Charges). • All items in the table which state ‘Y’ to ‘Applicable Charge?’ should be separated within your worked examples table and should remain

unchanged. These are identified as bold in the table to allow customers to easily identify consistent rows which are applicable to any water company.

• For any blank cell within the column ‘Applicable Charge?’, you should state whether or not it is applicable depending on the structure of your charges. If a charge item is not applicable, a ‘N’ should be placed in the column with ‘N/A’ across the charge item cells.

• Should you have additional charges which relate to an overall charge in Bold (i.e. Connection Charge or Mains Connection charge), you should include the rate in the table where it states ‘sub-charge 1,2,3…’ so that customers are able to relate the charges back to individual charging arrangements documents. The worked examples should reflect any ancillary charges which will be included in that part of work, i.e. thrust blocks.




12

• Clearly identify that the worked examples assume that all contestable sewerage delivery activities are completed by a third party. Any fees associated with these activities, i.e. Section 106 sewer connection vetting fee, should be itemised under ‘Other Charges’.

• As individual water companies publish their own contestability summary documents, where an activity within a worked example table is not a contestable activity or is deemed irrelevant for a NAV company, you should grey these out.

• Present infrastructure charges in full, i.e. before any applicable reductions, for example an infrastructure credit or water efficiency incentive. However, should a Water Company offer such incentives, you should make this clear in the footnote of the worked example.

• Present all charges exclusive of VAT.

Scenarios in detail

The following pages in this document set out each scenario in detail, along with the standard format for presenting the applicable charges.

In each of the scenario tables, "Alternative Delivery Method" and the relevant charges presented under that heading assume that an SLP or NAV performs all contestable elements of the work, including design, and incurs the costs associated with these activities.




13

Scenario 1: Single connection to a house from an existing main

This worked example provides charges for a single connection to an existing water main of 90mm diameter polyethylene (PE). If applicable, the worked example should include the associated charges for a single property connection to an existing sewer, which is completed by the Developer Customer. These charges are specified under ‘Other Charges’.

Within construction costs, this includes: Service pipe installation; Boundary box fitting; Meter installation; Excavation; Reinstatement

Pipework:

• 25 – 32mm diameter PE pipe • 4m pipework in road

Traffic management assumes the road (Type 3-4) is 40mph, has two lanes and does not require a road closure or lane closure. Two-way automated lights are required. There is also an assumption that the only payable council charges are for permitting.
